We're thrilled at your interest in Nafi!
Nafi is currently a single developer passion project by @CAD97. We appreciate your interest, but for practical reasons it's unlikely we'll be able to accept large contributions at this time. Smaller contributions (e.g. localized fixes/improvements) are generally greatly appreciated!
The best way to contribute to the project currently, however, is to try it out and report back on how that went; what went well, what went wrong, what could have been better, etc. We can't guarantee that we'll respond to all such experience reports, but we do read them all.
By contributing to the project, you grant license to said contribution as defined by the terms of the applicable license. Projects under the @nafi-lang organization typically use the MPL-2.0 license.
